是否有任何等效的填充解析服务器

Question

我创建了这样的主题

  const subject = new Subject({
      subject_name
    });
  subject.save();

然后我创建了老师

const teacher = new Teacher({
      teacher_name:'teacher neme',
      teacher_age:34,
      subject:'wGvTu03HQd'
    });
teacher.save();

当我尝试使用

获取教师对象时

let query = new Parse.Query(Teacher);
let a = await query.get(objectId);
console.log(a.get('subject'))

我明白了

ParseObjectSubclass { className: 'Subject', _objCount: 1, id: '8sB8uibifQ' }

有没有一种方法可以在不使用的情况下从主题对象中获取数据

let query = new Parse.Query(Subject);
let a = await query.get(objectId);

因为它和老师有关系，比如在猫鼬中填充？

Answer 1

是的。你可以使用include函数：

let query = new Parse.Query(Teacher);
query.include('subject');
let a = await query.get(objectId);
console.log(a.get('subject'))
